Aimshot 6.5prc/300prc Rifle - Arbor For Use W/.223 Boresight

The Aimshot 6.5prc/300prc Rifle Arbor for use with .223 boresight is a precision alignment tool engineered for long-range shooters, gunsmiths, and tactical professionals who demand absolute bore consistency before live-fire validation. This arbor adapter bridges the gap between common .223 boresight equipment and modern magnum rifle platforms, eliminating costly ammunition waste during initial scope zeroing and barrel tuning. Whether you're building a precision long-range system, conducting field maintenance, or validating headspace and bore alignment on 6.5 PRC or .300 PRC platforms, this arbor delivers the repeatability and accuracy critical to mission success.

Designed as a drop-in adapter, the Aimshot arbor leverages your existing .223 boresight laser or mechanical system, converting it to interface safely with larger magnum bores without alignment drift or chatter. The precision-machined arbor ensures concentricity within tight tolerances, critical for distinguishing true bore deviation from scope misalignment—a distinction that separates a properly zeroed rifle from one that holds inherent accuracy limits. At just 0.1 lbs and measuring 6.65 x 1.25 x 4.15 inches, the arbor remains compact enough for field packs or range bags, reducing logistics burden while maintaining professional-grade functionality.

Law enforcement precision rifle teams, military armament specialists, and civilian long-range competitors benefit most from this adapter when establishing baseline accuracy on 6.5 PRC or .300 PRC rifles before optic mounting and zeroing. Installation is straightforward: insert the arbor into the rifle's bore, align your .223 boresight laser, and proceed with scope mounting relative to confirmed bore axis. This product integrates seamlessly with standard AimShot laser bore sighting systems and mechanical arbor setups, making it an essential addition to any serious precision rifle maintenance kit.
